Child Medical Expense Subsidy: Eligibility & How to Apply [2026]

The child medical expense subsidy is a program where the municipality covers your child out-of-pocket medical costs (called nyuyoji iryohi josei or maru-nyu / maru-ko depending on the area). Children of foreign residents who are registered and enrolled in health insurance are also covered.

① Who is eligible

• A child registered as a resident in that municipality and enrolled in health insurance
• The covered age differs by municipality (preschool / through junior high / through the fiscal year they turn 18, etc.)
• Some municipalities have income limits or a small co-payment (a few hundred yen per visit)

② How you use it

Show the medical certificate (jukyusha-sho) issued after applying, together with the health insurance card, at clinics and pharmacies. Your counter payment is free or reduced (some areas pay first and refund later).

③ How to apply

Apply at your municipal office, soon after birth or moving in.

• The child health insurance card
• Applicant (guardian) ID (Residence Card, etc.)
• Something showing the My Number

For your child's sudden illness at night or on holidays, check night and holiday emergency care (#8000 and after-hours clinics).

If you are a single-parent household, Child Rearing Allowance for Single Parents in Japan may also be available.
